Application note

PCB design guidelines for the STM32W108 platform

1

Introduction

STMicroelectronics provides a IEEE 802.15.4 product design engineer with a number of

paths towards the successful design of a IEEE 802.15.4-compliant solution based on the

STMicroelectronics STM32W108 family of system-on-chip (SoC) platforms. The

STM32W108xx kits contain software, hardware, and documentation designed for

developers to create applications efficiently on a tested and controlled platform. Once the

design team is familiar with ST's STM32W108xx products and the available IEEE 802.15.4

software libraries and stacks, the next step in the design path involves designing application-

specific hardware to meet product requirements.

This application note is intended to accompany the reference designs and provide detailed

information regarding the design decisions employed within STMicroelectronics designs. In

addition, it details the design guidelines for developing an application-specific IEEE 802.15.4

design using an STM32W108xx device.

After reading this document, developers should be able to successfully implement a design

with an STM32W108xx device. For further information, visit the STMicroelectronics web site

at www.st.com/stm32w.

Due to the application-specific nature of STMicroelectronics reference designs, ST

recommends that hardware designers familiarize themselves with the most recent reference

design available. This document is applicable to the following STM32W108xx kits:

●

STM32W108xx starter kit (part number: STM32W-SK)

●

STM32W108xx extension kit (part number: STM32W-EXT)

●

STM32W108xx low-cost RF control kit (part number: STM32W-RFCKIT)

Note:

The STM32W108 Reference Design is built on a 4-layer, FR-4 epoxy PCB.

The STM32W108-based Reference Design includes the following elements:

While the Reference Design includes most of the information required to start an

application-specific design, if additional items needed, please contact STMicroelectronics
